Parts for your 2016 Subaru Legacy-Thrust bearing

2016 Subaru Legacy thrust-bearing: what it is, if it’s there, and how to look after it

Yes, the 2016 Subaru Legacy does use a thrust bearing — but it’s the engine’s crankshaft thrust bearing, not a clutch “throwout” bearing. The 2016 Legacy in AU/NZ markets runs a Lineartronic CVT, so there’s no manual clutch release bearing to worry about. Subaru’s factory service manuals for the 2015–2018 Legacy/Outback (Engine sections for FB25 and EZ36: Crankshaft/Main Bearing – Inspection) specify an integrated thrust bearing within the main bearing set to control crankshaft end float. The CVT sections also confirm there’s no clutch release mechanism in these models. Those technical references make the thrust bearing relevant to the engine, but not a routine service item.

In the Legacy’s flat-four (FB25) or flat-six (EZ36), the thrust bearing is part of the main bearing assembly. Its job is simple but critical: keep the crankshaft centred front-to-back, manage axial loads from the torque converter and accessory belt forces, and maintain proper alignment of the rotating assembly. It rides on a pressurised oil film, when oil quality drops or axial loads get excessive, the bearing can wear and crank end play increases.

Day to day, it’s not something that needs scheduled replacement. Smart maintenance is about prevention:

• Stick to the correct-spec engine oil and change intervals, clean oil protects the thrust faces.
• Keep the cooling system and CVT healthy to prevent overheating that can spike converter thrust loads.
• If towing or driving in hot conditions often, consider more frequent fluid checks as per Subaru guidance.

What might tip an owner off? Clues include a recurring rear main seal leak, fine metallic in the oil, a dull knock when shifting between Park/Neutral and Drive, or visible in–out movement of the crank pulley. A technician will confirm by measuring end float with a dial indicator against factory spec.

If replacement is needed, it happens during an engine strip-down. The workshop will inspect the crank’s thrust surfaces, fit the correct-grade main bearing set (with thrust halves), verify end play, and check related items like the flexplate and converter fit-up. It’s a specialised job that benefits from genuine parts, proper torque sequences, and rechecking clearances after the first heat cycle.

Bottom line: the 2016 Legacy absolutely has a thrust bearing — it’s just tucked inside the engine, doing quiet, vital work. Look after the oil and cooling, and it should last the life of the motor.

Does a 2016 Subaru Legacy have a clutch thrust/throwout bearing?

No. These models use a Lineartronic CVT, so there’s no manual clutch and no throwout bearing. When people mention a “thrust bearing” on this car, they’re talking about the engine’s crankshaft thrust bearing inside the bottom end.

What are the signs the crankshaft thrust bearing might be worn?

Tell-tales include a heavy knock when shifting from Neutral to Drive, repeated rear main seal leaks, glittery metallic in the oil, and visible fore–aft movement of the crank pulley. A mechanic can measure crank end float against the Subaru spec to confirm.

Is thrust bearing replacement part of regular servicing?

Not at all. It’s only addressed during an engine rebuild or if end float is out of spec. Routine care is about prevention: correct oil, on-time services, healthy cooling, and CVT maintenance appropriate to use conditions.
